Abstract
Results are presented for a number of window materials, color filter glasses, birefringent crystals, and optical fibers. The transmission loss caused by exposure to Co60 gamma or 10-MeV electron radiation is tabulated over the 400–900-nm wavelength region. The transmission loss is greatest at the shorter wavelengths, and its rate is maximum for most materials at dosages greater than 105 rad (Si).
